Nullability of reference types in type of parameter 'arg' of 'Task ReceiverBase.HandleEventAsync(EventCallbackWorkItem item, object arg)' doesn't match implicitly implemented member 'Task IHandleEvent.HandleEventAsync(EventCallbackWorkItem item, object? arg)' (possibly because of nullability attributes).

Non-nullable field '_jsRuntimeCommonApi' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Dereference of a possibly null reference.

Dereference of a possibly null reference.

Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call.

Nullable value type may be null.

Dereference of a possibly null reference.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
